SHOE PRESS Filed Nov. 19, 1932 2 Sheets-Sheet 2 l@ E552:============E VII/IA I Patented Dec. 29, 1936 UNITED, STATES PATENT OFFICE 2 Claims.

The present invention relates to shoe presses,

and more particularly to a hand press for cementing soles to shoes.

,Considerable difficulty has been encountered in the construction of shoe presses of the present type in that it is very easy to put sufficient pressure between the bridge of the press'and the base, so that the press will break at the corner.

It will be readily evident that in a direct press where a strain is produced between opposite parts of the press which strain may be made very great depending upon the strength of the operator, that it is very easy to exceed the breaking point of the apparatus.

In order to overcome this difficulty, the present press has been designed with a double arch so that each individual press element is strengthened on both sides. In addition to this the base and the top of the frame are cast in one piece, and the base is so designed that removable pans may be used.

It should also be noted that in the present press, a gauge is provided, and that the operator may readily see when the pressure in the pan is the desired amount.

The pan has inside of it a bladder, and may be covered at the'top by a piece of leather which is secured in place by means of a clamping ring clamping around the edge of the pan. The pan has a flange extending around its edge in one place and thus the clamping ring easily holds the top cover firmly on the pan. Further than this it should be noted that the press element,

includes an adjustable member to properly adjust the position of the pressing points on the last and therefore allows the press to be used for a great variety of sizes of shoes.

A heating coil may be inserted at the top of the pan in order to furnish heat to dry the cement after the shoe is once set in place. The bridge element pressing upon the last is designed to be held by the screw of the press in a manner which will be described below. Further advantages will appear from the description taken in connection with the drawings in which:

Figure 1 shows a plan view of the invention with one pan removed.

Figure 2 shows a side elevation.

Figure 3 shows a sectional view on the line 3-3 of Figure 1.

Figure 4 illustrates a, detailed modification, and

Figure 5 shows'a further modifying detail.

In Figures 1 and 2 the press comprises a frame I having side arches 2 and 3 and a center supporting arch 4. The section of the arch may be a T section orany other type desired.

At the center of each arch is a bearing 5 and 6 respectively which arethreaded to receive the screws 1 and 8 by which means pressure is exerted against the last through the turn of the hand wheels 9 and I respectively. 1

At the end of the screws 1 and 8 is carried a bridge element H shown partly in section at the left of Figure 2.

The bridge element l l is supported on the screw by means of a T shaped groove as indicated in Figure 4, in which a stud l3 formed at the end of the screw with a head I4 is positioned. The, screw is held in place by means of a pin l at the end'of the T shaped groove l2. The T shaped groove is made in the upper part of the element [6, the lower part of which is formed with a slot I! having external extending flanges l8 in which the bridge element ll may be moved back and forth. The bridge element ll therefore may be adjusted to the desired position, to the right or to the left as shown in Figure 3. V

The bridge element II has integral with it a forward foot or support l9 and an adjustable rear support which may be moved over the lower flange 2! of the bridge. The upper flange 22 works in the slot H.

In the modification shown in Figure 4 and the support over the bridge shown in Figure 2, the screw is readily turned independently of the bridge.

In Figure 3 the element l6 as shown is provided with an upwardly extending arm 24', so that the lower bridge element will not turn. The base of the frame I as indicated in Figures 2 and 3 is supported in three parallel lines by the edges 24, 25 and 26 as well as in a center supporting boss 21 indicated in Figure 3. A pan 28 as shown to the right of Figure 1 is placed in the base of the frame and is supported therein in two side fins, one of which, as indicated at 29 in Figure 3 is at either side of the pan resting upon the corners 30 and 3| as indicated in Figure 1. The pan is also supported on the base of a center foot 32 which rests upon the flat portion 33 indicated in Figure 1.

The pan is somewhat dished as indicated in Figures 2 and 3 and has a side flange 34 running around in a horse shoe shape as indicated perhaps more clearly in Figure 1. A bladder is positioned within the pan and on top of this is a leather or other suitable cover 36, the edges of which extend over the flange 34, and are clamped in place by means of the clamping ring 31 fitting over the flange and held firmly to it by means of the bolts and nuts ",etc.

The bladder has an outlet valve 39 in the stem 40 which passes through the pan and connects with the bladder. A T shaped union 4| provides a connection for the pressure indicator 4! which is mounted to the front apron 43 of the pan by means of a small shelf 44 on which the guage rests.

As indicated in Figures 1 and 5 beneath the leather top 36 a heating pad 45 may be used which preferably has a heat insulating cover at its lower side. The pad 45 may be used beneath the leather pad 36 or upon it if it is desired to make the heating more direct.

As indicated in Figure 3 a last 46 is placed in the shoe, the forward foot I! being adjusted for the toes and the rear foot 20 being adjusted in and out to be approximately positioned for the heel. The shoe with the last in it is placed upon the pan which is already inflated and the hand wheel is turned down until the pressure has increased the desired value as indicated on the indicator or until sufllcient tension is obtained to hold the sole firmly against the bottom of the shoe.

In the present process the shoe may be left in the press for a given time until the sole is properly cemented. If it is desired to hasten the drying or cementing process a small amount of heat is applied by use of the heating pad 45.

Having now described my invention, I claim:

1. In a pneumatic press for shoe soles, a base, a flexible air container, means mounting said container on said base, a bridge element mounted over said base, a compressional screw threadingly engaging said bridge element, means positioned at the lower end of said compressional screw for acting upon a shoe last, said means comprising a second bridge element having its bridge extending substantially perpendicular to the first bridge but in a different plane, and means supporting said second bridge element at the end of the compressional screw comprising a third independent element. having a downwardly extending slot with inwardly projecting flanges engaging corresponding projections at the sides of the second bridge element, means provided at the top of said independent element for engaging the end of said compressional screw, said means including a non-threaded portion at the end of the compressional screw having a groove therein and an opening in the independent member shaped to receive the end of the compressional screw, and a pin positioned across said opening to prevent the independent member from coming away from the compressional screw.

2. In a pneumatic shoe press for fixing soles to shoes having a last holding the shoe and adapted to be forced downward to provide pressure between the sole and the shoe, a removable base comprising a pan element having a recessed central portion, means having a flat surface border ing said central portion and having downwardly extending webs forming an apron supporting the pan, a platform extending from the forward part of said pan and forming a gauge support, a pneumatic cushion positioned in said central portion, a covering positioned over said cushion and extending over said flat surface, and means positioned over said cover on the flat surface for fastening said cover in place, said gauge support being adapted to receive a pneumatic gauge.
